Mitochondrial fission is the process by which mitochondria divide or segregate into two separate mitochondrial organelles. Mitochondrial fission is counteracted by mitochondrial fusion , where two mitochondria fuse together to form a larger one. [ 1 ]
The significance of mitochondrial fission and fusion is distinct for nonproliferating neurons, which are unable to survive without mitochondrial fission. Such nonproliferating neurons cause two human diseases known as dominant optic atrophy and Charcot Marie Tooth disease type 2A, which are both caused by fusion defects.
Nuclear data represents measured (or evaluated) probabilities of various physical interactions involving the nuclei of atoms. It is used to understand the nature of such interactions by providing the fundamental input to many models and simulations, such as fission and fusion reactor calculations, shielding and radiation protection calculations, criticality safety, nuclear weapons, nuclear ...
The first Soviet fusion bomb test, RDS-6s, American codename "Joe 4", demonstrated the first fission/fusion/fission "layercake" design, limited below the megaton range, with less than 20% of the yield coming directly from fusion. It was quickly superseded by the Teller-Ulam design. This was the first aerial drop of a fusion weapon.

Scientists already knew about alpha decay and beta decay, but fission assumed great importance because the discovery that a nuclear chain reaction was possible led to the development of nuclear power and nuclear weapons. Hahn was awarded the 1944 Nobel Prize in Chemistry for the discovery of nuclear fission.
For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Like nuclear fusion, for fission to produce energy, the total binding energy of the resulting elements must be greater than ...
